Quoting Douglas Anderson (2021-03-04 15:51:59) > The clock framework makes it simple to deal with an optional clock. > You can call clk_get_optional() and if the clock isn't specified it'll > just return NULL without complaint. It's valid to pass NULL to > enable/disable/prepare/unprepare.

This seemed OK to me.
